Embodiment 1

[0026] figure 1 It is a schematic flow diagram of a method for preparing polysaccharides of Sagittarius sativa in the embodiment of the present invention, such as figure 1 As shown, the preparation method of the polysaccharides of the sand grass includes:

[0027] Step 10: pulverizing the dried sphaeria to obtain sphaeria powder;

[0028] Specifically, the dried sphaerifolia is taken and crushed, and the crushed sphaeria powder is passed through a 40-mesh sieve to obtain the sieved powder that meets the requirements.

[0029] Step 20: extracting the sandy grass powder, suction filtering, and concentrating to obtain the sandy grass crude polysaccharide solution;

[0030] Further, the extracting of the sandy grass powder, suction filtration, and concentration to obtain the sandy grass crude polysaccharide solution also includes: using petroleum ether to reflux the sandy grass powder to remove fat-soluble compounds, and using ethanol Refluxing for depigmentation treatment; mix...

Embodiment 2

[0043] This embodiment provides a plant salt-resistance regulator, said salt-resistance regulator comprising the saliva polysaccharide described in claims 1-6.

[0044] Specifically, the embodiment of the present invention provides a new application of the polysaccharide of Centipeda salina, which can be used to prepare a plant salt-resistant regulator, and at the same time, compound the polysaccharide of Centipede salina and a surfactant to make a salt-resistant regulator. It can improve the comprehensive resistance of plants to salt stress and ensure the normal growth and development of plants. The polysaccharides of Citronella can regulate ion transport in plants to improve the salt resistance of plants. On the one hand, the polysaccharides of Citronella can store excess Na+ in the roots to reduce the stress of Na+ on stems and leaves, so as to ensure the physiological functions of plant leaves. ; On the other hand, the polysaccharides of the plant can induce plants to tran...

Embodiment 3

[0051] In order to understand more clearly the plant salt resistance regulator provided by the embodiment of the present invention, the embodiment of the present invention will be described in detail below with specific examples.

[0052] Dissolve 100 mg of the saliva polysaccharide in 800 ml of distilled water, stir evenly, and finally adjust the volume to 1 L with distilled water, and after stirring uniformly, make the concentration of the saliva polysaccharide 100-1000 mg / L to obtain the Anti-salt modifier A; or add surfactants respectively to the anti-salt modifier A, and the surfactants are selected from one or more mixtures of Tween series, Span series, OP series and / or NP series , so that the concentration of the surfactant is 1000-20000mg / L, and the anti-salt regulator B is prepared.

[0053] Spray the wheat seedlings in the seedling stage by using the salt-resistant regulator A or B, the specific process is: sterilize, soak, and accelerate germination of the wheat see...

Abstract

The invention discloses a tournefortiasibirica polysaccharide preparation method and a plant salt-resistant regulator. The tournefortiasibirica polysaccharide preparation method comprises the following steps: crushing dried tournefortiasibirica to obtain tournefortiasibirica powder; performing extraction, extraction filtration, condensation on the tournefortiasibirica powder to obtain a coarse tournefortiasibirica polysaccharide solution; performing deproteinization on the coarse tournefortiasibirica polysaccharide solution to obtain a deprotein coarse tournefortiasibirica polysaccharide solution; performing alcohol precipitation and lyophilization on the deprotein coarse tournefortiasibirica polysaccharide solution to obtain coarse tournefortiasibirica polysaccharide; removing pigment ofthe coarse tournefortiasibirica polysaccharide through macroporous resin to obtain tournefortiasibirica polysaccharide, the technical problem that green natural salt resistant agent taking the tournefortiasibirica polysaccharide as raw material is not found in the prior art is solved, the tournefortiasibirica polysaccharide preparation method has the advantages of simple extraction process, safe and environmental protection and remarkable effect, and is suitable for being applied to the technical effects of development and application of the plant salt-resistant regulator.

Description

technical field [0001] The invention relates to the technical field of plant regulators, in particular to a method for preparing polysaccharides from Phyllostachys sativa and a plant salt-resistant regulator. Background technique [0002] Tournefortiasibirica (Tournefortiasibirica) is a perennial wild herb of the Boraginaceae genus Tournefortiasibirica, also known as Zidancao, Siberian Zidan, etc. Sandgrass is a species in central Asia in the temperate zone. It is mainly distributed in the coastal and inland areas of China and neighboring countries at 30°-45° north latitude. Most of them are in the coastal area. Barren resistance. Sand grass not only plays an important ecological role in windbreak and sand fixation, beach protection and vegetation restoration, but also can be used as medicine, feed, honey plant and green manure, and has broad application prospects in agricultural production. It is reported that the vegetative growth period of S. sativa has higher content o...
